Thank you for purchasing Xit 404’s Canon Macro EF USM 100mm
Focus Ring-Gear set or Teleconverter Gears. On the back is our
warranty information to help you prolong the life of this product.
Assembling the Focus Ring and Gear
Look at the drawing to the left and note which end of the lens the
Focus Ring slides onto. Then follow the instructions below.
1. Make sure your Focus Ring is in the unlocked position. Slide the
Focus Ring onto your lens from the front and align the front of the
gray ring with the edge of the rubber ring on the lens, see picture
on left.
2. Once on the lens, grasp the Focus Ring, then press and hold the
gray latch on the Focus Ring while twisting the gray and red rings
in opposite directions until the white dots line up. (Note: the locked
icon). The Focus Ring is now locked onto the lens.
3. Slide the Gear on from the back of the lens. Align the white dot
on the Gear with the unpainted red dot on the Focus Ring. Then
press the two parts together. Once the the two parts are fully mated,
while holding the Focus Ring with one hand twist the Gear until the
white dots line up (note: the locked icon). The Gear is now locked
onto the Focus Ring.
4. If you are using a teleconverter follow step 3 to first attach the 1.4X
or 2X Extension Ring in the same way as the Gear then repeat the
step to attach the Gear. The Tele Extension Rings were designed to
used with either the Tamron SP AF or Kenko Pro 300 DG
tele-converters.
Disassembling the Focus Ring and Gear
1. Remove the Gear by pressing and holding the red latch on the Gear.
Then twist it until the white dot on the Gear is lined up with
undpainted red dot on the Focus Ring. (Note: the unlocked icon).
2. Pull the Gear Ring off the lens. If you used an Extension Ring pull
it off next.
3. Remove the Focus Ring by reversing steps 1 and 2 above. The
white dot and the unpainted red dot will not be lined up after step 2,
allowing you to slide the Focus Ring off your lens.

WARRANTY INFORMATION
FDM parts - a brief description
Xit 404 manufactures a number of its parts using a process called Fused Deposition Modeling (FDM). This process involves extruding a thread of plastic and laying it down
in thin layers to build a part. This enables us to supply you products that enhance your underwater photography and videography.
Care and Maintenance
The FDM part is impact resistant and will withstand most drops from table height. However, as with all plastic parts, they cannot withstand excessive pressure and
force without breaking. Being careful means handling the product during assembly with a light touch, do not force.
If your part gets wet let it drip-dry for about an hour. If you have to pack it before it is dry then wrap it in something absorbent such as a paper towel, tee shirt or sock
and put it into a plastic bag. This will keep your other parts from getting dripped on.
FDM Plastic Part Warranty
FDM parts are guaranteed to be free of manufacturing defects for a period of one year from date of purchase. Unnecessary force can cause excessive wear and
possibly break the parts voiding warranty. Damaged or broken parts will be inspected. If Xit 404 determines that the parts were misused or abused, warranty will be void.
Valid purchase receipt isrequired for all warranty claims.
